Abstract
The theory of anthropogenic global warming (AGW) enjoys considerable consensus among experts. It is widely recognized that global industrialization is producing an increase in the planet's temperatures and causing environmental disasters. Still, there are scholars – although a minority – who consider groundless either the idea of global warming itself or the idea that it constitutes an existential threat for humanity. This lack of scientific unanimity (as well as differing political ideologies) ignites controversies in the political world, the mass media, and public opinion as well. Sociologists have been dealing with this issue for some time, producing researches and studies based on their specific competencies. Using scientometric tools, this article tries to establish to what extent and in which capacity sociologists are studying the phenomenon of climate change. Particular attention is paid to meta-analytical aspects such as consensus, thematic trends, and the impact of scientific works.

This study compares the dominant narratives on the future of work. It shows that a paradigm shift is underway in the context of scenario analysis, as a consequence of the impetuous development of robotic and computer technologies. Near the two main traditions of thought, which respectively emphasize 'technological unemployment' and 'compensation,' a third vision of the future is emerging that examines trends and scenarios ignored by traditional economic theories. This third narrative places particular emphasis on the 'hollowing out' phenomenon. It states that automation will not cause the complete disappearance of work, but only of the average qualified one. In other words, in the absence of corrective interventions, the society of the future will be characterized by the presence of a minority of privileged citizens, who will be able to fully enjoy the fruits of automation, surrounded by a majority of citizens engaged in precarious and degrading jobs. This study shows that the third narrative is only relatively new. Socio-technical expectations went full circle, reviving a prognosis already present in Karl Marx's works.

Abstract
In recent years a debate has developed over the ties between Friedrich Nietzsche's ideas and transhumanism. This article clarifies some issues at the meta-level of the discussion. Firstly, the author provides a scientometric analysis of research trends to show the relevance of the topic. Secondly, he distinguishes between two analytical perspectives, which he calls 'noumenal' and 'phenomenal.' Thirdly, by taking the phenomenal perspective, the author shows that transhumanism can be classified into four different categories, namely: quasi-Nietzschean, Nietzschean, a-Nietzschean, and anti-Nietzschean. Finally, he provides historical examples of each single type of transhumanism. This way, the article also contributes to the history of transhumanist thought.

Abstract
This article provides a detailed description of robotic weapons and unmanned systems currently used by the U.S. Military and its allies, and an ethical assessment of their actual or potential use on the battlefield. Firstly, trough a review of scientific literature, reports, and newspaper articles, a catalogue of ethical problems related to military robotics is compiled. Secondly, possible solutions for these problems are offered, by relying also on analytic tools provided by the new field of roboethics. Finally, the article explores possible future developments of military robotics and present six reasons why a war between humans and automata is unlikely to happen in the 21st century.
